A cloud architect is designing a new application that requires high availability and disaster recovery across multiple geographical regions. Which cloud deployment model would best support these requirements?
- APublic cloud
- BHybrid cloud
- CPrivate cloud
- DCommunity cloud
Show answer & explanationAnswer & explanation
Correct answer: A. Public cloud
Public clouds offer a globally distributed infrastructure with multiple regions and availability zones, inherently supporting high availability and disaster recovery across diverse geographical locations.
Why the other options are wrong
- B. Hybrid clouds combine public and private, but the core capability for global distribution comes from the public cloud component.
- C. Private clouds are typically deployed within a single organization's data centers, limiting geographical distribution for disaster recovery.
- D. Community clouds are shared by specific organizations with common concerns, not primarily designed for broad geographical distribution and disaster recovery for a single entity.
Public Cloud
A cloud deployment model where computing services are delivered over the internet by a third-party provider, offering shared infrastructure and global availability.
- Owned and operated by a third-party cloud service provider.
- Resources are shared among multiple organizations.
- Offers high scalability, elasticity, and global reach.
Memory trick: Public clouds are like a global utility, always on, everywhere.
